Japan developed the world's first rechargeable straight tube LED light

According to Japanese media reports, Japan Cybercoin Co., Ltd. has recently developed the world's first rechargeable straight-tube LED energy-saving lamp, which can be continuously illuminated for a long time after power failure, and the longest sustainable illumination is 12 hours.

The LED energy-saving lamp has a built-in lithium-ion rechargeable battery. The lamp will charge itself under normal power supply conditions. After 3 hours, it will automatically switch to battery-powered mode illumination. After two hours, it will switch to the normal mode and cycle lighting accordingly.

Since the battery lighting mode does not require additional power consumption, its actual power consumption is only 30% of the same wattage of ordinary fluorescent lamps, and 60% of the same wattage of ordinary LED lamps. However, the price is high, at 19,800 yen (about 1,500 yuan).
